The nation's disaster agency says it was an aftershock of the magnitude 8.1 earthquake that hit the state on 7 September, in which at least 90 people died.

A series of 4.0 magnitude earthquakes have been reported off Oaxaca’s coastline during the night. Juchitan, the city in Oaxaca that suffered the most destruction and deaths during the earlier quake, has registered three more between magnitudes 4.8 and 5.0.

The Mexican President Enrique Pena Nieto said structures which were affected by the previous quake have suffered more damage including the bridge of Ixtaltepec.

Mexico City did not immediately appear to sustain significant damage, the country's office of the secretary of public security said.

But rescue efforts at a collapsed residential building in the Tlalpan neighborhood of the Mexican capital were suspended because of a risk that buildings already impacted by Tuesday's quake could collapse.

Operations are ongoing at some of the dozens of houses and offices which were hit by and they could last "for at least two more weeks," Luis Felipe Puente, Mexico's civil protection coordinator, told CNN affiliate Foro TV.

The 7.1 magnitude earthquake devastated the country's central region. At least 307 people died and dozens are still missing.
